Tourbillon Chiming Jump Hour
The movement of the Tourbillon Chiming Jump-Hour AK-03 is completely novel, since the combination of tourbillon with a digital jumping-hour indication and an hour strike is unprecedented in commercial fine watchmaking.
The Tourbillon Chiming Jump-Hour AK-03 applies extreme precision to its incorporation of both visible and audible time indications. As the name suggests, the jumping hour indication is combined with a gong strike (equipped also with silent mode). These are accomplished via separate mechanisms, and Rexhep Rexhepi has designed the AK-03 specifically so that the chime occurs at the same instant in which the hour makes its jump.

Movement construction of the Tourbillon Chiming Jump-Hour AK-03 is highly symmetrical, with radially aligned components. Aside from aesthetic value, this demonstrates the extreme sophistication of Rexhep Rexhepi’s approach to movement construction.

The Tourbillon Chiming Jump Hour is the first AkriviA creation with a voice, formed by the strike of a steel hammer against a curved gong
